DETAILED DESCRIPTION

[0018] In order to make the purpose, principle and structure of the utility model more clear and explicit, the following further elaboration is made in combination with the drawings and specific embodiments.

[0019] Embodiment one: the embodiment provides a supergravity mixing processing equipment.

[0020] Referring to Figure 1 、 2 , 3, the structure of the processing equipment comprises a closed housing 1, and the inside of the housing 1 is divided into an upper cavity and a lower cavity by a horizontal partition plate. An electric motor 2 and a coupling 3 are installed in the upper cavity, and the electric motor 2 is connected with a main shaft 7 arranged vertically in the lower cavity through the coupling 3 to realize power transmission.

[0021] A fixedly installed outer cylinder 4 is arranged in the lower cavity, a liquid inlet 12 perpendicular to the outer cylinder 4 by 90° is arranged on the side wall of the outer cylinder 4, a volute 5 is arranged at the top of the outer cylinder 4, the top of the outer cylinder 4 is sealingly connected with the volute 5, and an air inlet is arranged at the lower part of the outer cylinder 4 for air inlet.

[0022] A plurality of annular isolation plates 11 are arranged on the inner wall of the outer cylinder 4 in an axial direction, the annular isolation plates 11 are used for receiving liquid thrown to the inner wall of the outer cylinder 4 and increasing the contact area of the liquid with gas in the equipment, so that the liquid is mixed with the gas again, a plurality of liquid backflow grooves are arranged on the inner wall of the outer cylinder 4 at equal angles corresponding to the regions of the isolation plates 11, and the liquid backflow grooves are used for guiding the liquid to flow back to the bottom of the outer cylinder 4 quickly. The bottom of the outer cylinder 4 is provided with a liquid outlet 13.

[0023] The outer cylinder 4 adopts a barrel structure, which is beneficial to uniform distribution and efficient mixing of materials in the equipment while ensuring stability of the equipment. The backflow grooves are preferably 10mmx5mm in size and are arranged at four equal parts in the outer cylinder 4.

[0024] The main shaft 7 vertically penetrates the volute 5 and the outer cylinder 4, and the upper and lower ends thereof are fixed to the top of the volute 5 and the bottom of the outer cylinder 4 through bearing seats 6 respectively. The outer part of the main shaft 7 is coaxially sleeved with a main shaft cylinder 8, and a plurality of layers of inclined blades 10 groups are arranged on the lower part of the main shaft cylinder 8 in the circumferential direction. Each layer of blades 10 is distributed in a spiral around the axis of the main shaft 7 at an inclination angle of 55°. The lowest end of each blade 10 is the part that is first contacted by the liquid, which is referred to as a shear starting point 17. The highest end of each blade 10 is the part that is last separated from the liquid, which is referred to as a shear ending point 18. The shear ending point 17 and the shear starting point 18 of the adjacent layers of blades 10 are formed with a phase difference in the axial direction, thereby forming a continuous inclined shear channel. The electric motor 2 drives the main shaft 7 to rotate through the coupling 3, and the main shaft cylinder 8 on the main shaft 7 rotates with it. The centrifugal force is generated in the rotation, and the liquid and gas are lifted along the inclined shear channel under the action of the centrifugal force. At the same time, the liquid and gas can collide with the blades 10 of the upper and lower layers in the inclined shear channel. The liquid is atomized into droplets by the collision and is thrown onto the inner wall of the outer cylinder 4 from the main shaft cylinder 8.

[0025] The bearing seats 6 are arranged at the top of the volute 5 and the bottom of the outer cylinder 4 respectively, and are all waterproof sealed bearing seats 6.

[0026] A plurality of gas-liquid separation plates 9 are uniformly welded on the upper part of the main shaft cylinder 8 in the circumferential direction. The gas-liquid separation plate 9 adopts an airfoil cross section, and is used for dispersing the atomized liquid horizontally to the inner wall of the outer cylinder 4 to end the inclined lifting trend of the liquid and realize preliminary gas-liquid separation.

[0027] The volute 5 comprises a central inner circular flow channel 21 and a spiral outer circular flow channel 22 surrounding the outer side of the inner circular flow channel 21. An opening is arranged at the bottom of the inner circular flow channel 21, and an assembly gap is arranged between the opening and the top of the main shaft cylinder 8. A backflow gap channel 19 is arranged around the bottom of the inner circular flow channel 21. One end of the outer circular flow channel 22 is communicated with the inner circular flow channel 21, and the other end is connected with an air outlet 23. The air outlet 23 can be communicated with a vacuum pump pipeline, so that a negative pressure environment of-0.08 to-0.095 MPa is formed in the equipment through the vacuum pump. The through hole formed by the gap cooperation between the volute 5 and the main shaft cylinder 8 realizes the gas-liquid flow between the upper and lower cavities. The liquid backflow groove of the outer cylinder 4 and the backflow gap channel 19 of the volute 5 cooperate to ensure that the condensed droplets are efficiently guided back to the mixing area.

[0028] Preferably, in the utility model, the main shaft cylinder 8 can realize stable and efficient operation at a rotation speed of up to 1450 revolutions per minute. Through the continuous feeding and automatic discharging circulation mode, it is ensured that the solution in the equipment will not be left for a long time during the mixing of the processing solution. At the same time, the fluid resistance of the equipment during operation is extremely small, which is only 0.0003768 N through testing, which makes the equipment realize large liquid processing capacity while effectively reducing energy consumption and significantly improving production efficiency.

[0029] Preferably, the outer cylinder 4 in the shell 1 is also installed with temperature control meter, vacuum pressure control meter, air pressure control meter, frequency converter, PRC control cabinet and other equipment, which realizes the accurate monitoring and control of the equipment operation parameters.

[0030] The continuous feeding and automatic discharging cycle mode is adopted, the fluid resistance of the equipment is extremely small during operation, and the solution residue between the main shaft cylinder 8 and the outer cylinder 4 is less, which not only ensures the high stability of the processing quality, but also realizes low energy consumption while ensuring the liquid processing quality. The stable balance asymmetry of the equipment is less than 0.15g under the high-speed rotating motion of 1450r / min, thereby ensuring the stability and reliability of the equipment under high-speed operation state.

[0031] By increasing the diameter of the main shaft cylinder 8, the circumferential rotation of the main shaft cylinder 8 is enhanced, and the linear speed of the rotating part is effectively improved. The outer solution of the equipment is continuously sprayed into the supergravity mixing equipment by the quantitative pump, and the mixed solution is self-flowed into the finished product storage tank through the outer cylinder outlet of the equipment. This efficient operation mode significantly improves the processing efficiency.

[0032] The symmetrically arranged blades 10 are installed on the rotor of the main shaft cylinder 8, and a large number of experiments have verified that when the angle of the blade 10 is 55°, the efficiency of the mixed solution is ≥90%. The gas-liquid separation plate 9 on the upper part of the main shaft cylinder 8 ensures that the solution is uniformly separated and finally discharged. At the same time, the equipment can operate in a normal pressure (0.1013MPa) operating environment, which reduces the pressure requirement of the equipment operation and improves the applicability of the equipment.

[0033] The gap between the outer cylinder 4 and the main shaft cylinder 8 forms a channel, and the void fraction of the channel is accurately controlled at 0.5%. The annular isolation plate 11 is installed on the inner wall of the outer cylinder 4, which can effectively receive the atomized particle size of the solution thrown by the centrifugal force of the main shaft 7, meet the chemical processing demand of the void fraction solution capacity of 10m³ / h, and ensure the accuracy and efficiency of the processing process.

[0034] After the liquid is thrown by the centrifugal force of the main shaft 7, the blade 10 repeatedly throws the liquid from top to bottom into the atomized liquid drops, and the reflux groove installed on the outer cylinder 4 ensures that the liquid realizes self-reflux to the finished product storage tank outside the equipment under the action of gravity acceleration, which greatly improves the recycling rate and processing efficiency of the material.

[0035] The solution enters the channel of the device and is subjected to circumferential movement under the action of the high-speed rotating force of the rotor main shaft 7. The raw material is attracted by the rotating blade 10. The solution is subjected to bidirectional reciprocating movement in the rotating blade. The rotating blade gap causes the mist droplets to be lifted upward. The high-speed centrifugal force, the supergravity attraction and the force generated by the supersymmetry dimension jointly act on the solution, so that the mixing of the solution is more sufficient. The injection angle of the solution quantitative pump at the liquid inlet 12 is horizontally installed at 90°, so as to ensure uniform injection and efficient mixing of the solution.

[0036] The device can stably operate in a wide temperature range of 25℃ - 400℃, and can provide process solutions for dispersion, aggregation, combination, homogenization, oxidation, emulsification and other organic and inorganic substances (liquid-solid concentration; ≥100 / 30), to meet the needs of different chemical production processes, and has a wide application prospect.

[0037] Embodiment two: the embodiment provides a supergravity mixing processing system using the processing and mixing device.

[0038] Referring to Figure 4 , the processing system comprises a first supergravity device and a second supergravity device connected in series. The liquid inlet of the first supergravity device is connected to the material to be treated and the mixed liquid through a pipeline. The outlet of the air pump is directly connected to the air inlet of the first supergravity device through an air duct. The air outlet of the first supergravity device is connected to the air inlet of the second supergravity device through a serial pipeline, forming a continuous gas treatment channel. The liquid outlet of the first supergravity device is connected to the inlet of the transition tank. The outlet of the transition tank is connected to the liquid inlet of the second supergravity device through a pipeline by a delivery pump, realizing the stage delivery of the liquid. The liquid outlet of the second supergravity device is connected to the solution tank. The bottom outlet of the solution tank is connected to the liquid circulation loop. The main pipeline is connected to the liquid inlet of the first supergravity device. Branch pipelines are arranged in the middle section of the main pipeline. The branch pipelines are provided with mixing nozzles for injecting the material to be treated and the mixed liquid into the circulating liquid, forming a closed circulation treatment system. The devices in the system are connected through flanges.

[0039] Preferably, the material to be treated is concentrated chloride ions, the mixed liquid is desulfurization wastewater, and the solution tank can also produce by-products fly ash and desulfurization gypsum. The liquid circulation loop can realize the circulation of the chloride ion solution.

[0040] Embodiment three: the embodiment provides an embodiment for treating desulfurization wastewater of a coal-fired power plant by using the technical solutions of embodiments one and two.

After equipment treatment, the chloride ion concentration in the upper layer is reduced by more than 50%. Taking the operation data of May 23, 2024 as an example, the original chloride ion concentration is 150,000 mg / m³, and after treatment, it is reduced to 68,653 mg / m³, with an efficiency of 54%, and the equipment treatment time is only 2 minutes. This achievement not only solves the environmental protection problem of the power plant, but also reduces the wastewater treatment cost, improves the quality of by-product fly ash and desulfurization gypsum, and makes the chloride ion content meet the standard requirements.

[0051] A pharmaceutical company needs to accurately mix a variety of chemical raw materials in the process of drug synthesis. In the past, the use of traditional mixing equipment not only takes a long time, but also easily causes uneven mixing, affecting the purity and efficacy of the drug.
